HINGE.

Specification of Letters Patent.

Patented May 25, 1920.

Application led April 24, 1917. Serial No. 164,202.

T0 all whom it may concern.'

Be it known that I, ULYssEs GRANT Mo QUEEN, citizen of the United States, and resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinges generally and specifically to that class known as casement hinges. I do not wish it to be understood, however, that the invention is designed solely for use in connection with such structures as it may be advantageously employed in connection with swinging structures of various well known types that are adapted to slide vertically as well as swing on a supporting axis. y

In hinges of the sliding leaf-type, the knuckles of the mating leaves are capable of relative separation in order that a sliding action may be set up in the leaves when one leaf is raised from the other, prior to the opening of the hinge. To my knowledge, no provision has been made in this class of hinges for causing the knuckle portion of one leaf to be wholly interposed between the knuckles of the next leaf and in direct appreciable supporting contact therewith -whereby to strengthen the hinge and prevent the same from being strained under the weight of the easement when the latter' is opened.

The invention herein set forth clearly and specifically in the following has for its principal purpose, the provision of a pair of leaves normally arranged so that one leaf may freel slide on the other in fiat contact therewith when the hinge is closed and in carrying the invention into practice, I Hnd it advisable to provide one leaf with a plurality of knuckles and a second or mating leaf with a single knuckle, the latter having an extension normally disposed at one side of a similar extension on one of the knuckles of the other leaf and adapted, when the hinge is opened, to be superposed relatively thereof and in firm supporting contact therewith and arranged so that a horizontal base of said single knuckle comes against a horizontal surface of the lower knuckle 0f the said other leaf. In this manner the hinge is not only strengthened along the line of its axis and the leaves made responsive to the sliding movements of the easement, but the latter is very satisfactorily held against lowering when the hinge is opened and against undue sagging.

Another object of the invention is to provide means between the knuckles of one leaf for concealing the knuckle portion of the other leaf, preventing one'from tampering with the knuckles from the outside and also designed so as to simulate hinge knuckles which almost completely house said knuckle portion of the other leaf at all times. In this arrangement the relative separation of the hinge knuckles is not visible from the outside Iand the hinge is made to assume and maintain a graceful and symmetrical appearance at all times and the beauty of a hinge designed for interior work is not noticeably detracted from during the operation of raising one leaf from the other.

Among many other objects in view which will be apparent as the nature of the invention is better understood, I have designed a hinge which is simple of construction, strong and durable, and one wherein the several parts thereof can be readily assembled or disassembled as the occasion re quires.

l'n the drawings y Figure 1 is a perspective view of the hinge showing the several parts thereof separated for the purpose of proper illustration.

Fig. 2 is a side view thereof showing the sleeve in section.

Fig. 3 is a horizontal section on the line 3.3 of Fig. 2.

Fig. 4 is a perspective view of the hinge showing the leaves opened and the sleeve removed.

The hinge consists of two leaves A and B, the formerhaving a pluralityof knuckles l and 2, and the latter a single intermediate knuckle 3. The knuckle 2, has a xed cylin drical extension 4, which is similar in design to an extension 5, which depends from the knuckle 3. The length of the knuckle 3, including the extension 5, thereon is equal to the distance between the base of the knuckle l, and the upper surface of the extension 4. The leaves A and B, are co-extensive with each other and normally or in other words,

when the hinge is closed, the straight sides a-, of the extension 5, are directly at one side of the corresponding straight sides A, of the extension 4, and in free slid ing contact therewith. It will thus be observed that when the two leaves are closed against each other and the leaves in their normal relation, the upper end of the knuckle 3, is spaced from the lower surface of the knuckle 1. As soon as the surfaces a--5f, leave the surfaces 4a-4, the base of the extension 5, on said knuckle 3, comes in direct supporting contact with the upper surface of said extension 4, on the knuckle 2. When the leaf B, is turned in opening the easement, the horizontal edge 4b, of the extension 4, comes under the horizontal edge 5b, of the extension 5, giving continuity of the hinge knuckles throughout as will be apparent. This construction serves to securely sustain the weight of the easement when the latter is opened and the two leaves A and B, are positively held against sliding movement. A easement supported from a hinge of this type is also held against undue sagging incident to the substantial or appreciable bearing surfaces 4b and 5b, above referred to.

A housing is used for thelpurpose of concealing the knuckle edge of one leaf and the same is shown at 7, and is extended between the knuckles 1 and 2, of said leaf A. This housing is split along a continuous longitudinal line and is adapted to embrace the knuckle 3. In line with the extension 5, of the knuckle 3, the housing is provided with an opening 8, in order that the extension can be initially inserted in the housing and both leaves connected together when assembling the hinge. The housing is scored at G, so that the visible sections 6b, at the sides of the scored portion will appear to the eye as hinge knuckles. The transverse diameter of the knuckle 3 and its extension 5, is less than that of the main body of the knuckles 1 and 2, so that the housing comes flush with the said last mentioned knuckles. This also holds the housing from sliding with the leaf B, as the ends of said housing are confined against the adjacent portions of said knuckle 1 and extension 4. Vhen the hinge is closed, the opening in the side of the housing is covered by the leaf B and the walls 8, of said housing come directly against the opposite sides of said leaf. It then becomes extremely difficult to the casual observer to detect any broken or interrupted lines in the knuckle edge of the structure.l At no time is the unsightly separated condition of the knuckle made visible from the outside of the hinge. The knuckle 2, carries a fixed knob or cap 9. A pin 10, extends through all of the described knuckles and said pin is provided with a threaded boss 11, which fits in a correspondingly threaded socket 12, in the knuckle 1.

Through the fact that the housing 7, is

confined between the knuckles 1 and 2, it follows that the same is maintained in the same relatively fixed position upon the leaf B, at all times. lhen the leaves A and B, are closed against each other the adjacent portion 5, of the extension 5, is adapted to freely pass through the open side of the cxtension 4. Said open side is therefore parallel with the side of the leaf A.

As set fort-h, the hinge described herein, is designed particularly for use in connection with easements of the swinging and sliding type. In easement construction, the frame is usually provided with a stop-strip behind which the base of the easement rests when the latter is closed in the frame. It is therefore very essential that means be provided which will positively prevent the hinge from opening during the operation of raising the easement so as to prevent the latter from swinging against the mentioned well known stop-strip. The hinge leaves fully described herein, are free to slide in flat contact with each other during said operation of raising the easement and the surfaces 4-'4, and 51-5, are found most re* liable in preventing accidental turning of the easement during the raising operation. Much regard has been given this functional arrangement of parts and at the same time establishing simplicity, compactness, durability and an arrangement wherein said parts will be capable of serving the dual purpose set forth herein.

That is claimed as new isz 1. A hinge comprising a pair of leaves slidable one over the other in flat contact, knuckles on one leaf, a knuckle on the other leaf, a knuckle-receiving-housing interposed between the knuckles of one leaf and receiving the knuckle portion of the other leaf and concealing the same, and means for holding one of said leaves against sliding movement when the hinge is opened, the knuckle on said other leaf being spaced from one of the knuckles of the first leaf as and for the purpose specified.

2. A hinge for vertically movable and horizontally swinging easements comprising a pair of leaves connected together to slide one over the other vertically in flat relative contact, a plurality of knuckles on one leaf, means for holding the leaves against opening during the operation of sliding one leaf on the other, and a knucklereceiving-housing interposed between said knuckles and movable in a horizontal direction with the other leaf and concealingr the knuckle portion of said leaf.
